Rename PopupMenuAndroidNativeComponent.js to PopupMenuAndroidNativeComponent.android.js to fix CI

Summary:
This change renames `PopupMenuAndroidNativeComponent.js` to `PopupMenuAndroidNativeComponent.android.js`.

The reason is that, without the suffix, Codegen was reading the NativeComponent spec also for iOS, generating some invalid specs and making RNTester fail.

## Changelog:
[Android][Changed] - Rename `PopupMenuAndroidNativeComponent.js` to `PopupMenuAndroidNativeComponent.android.js`
